Nursing Elites

1. When a client with a history of atrial fibrillation is admitted with a new onset of confusion, which diagnostic test should the nurse anticipate preparing the client for first?

• A. Electrocardiogram (ECG)
• B. Chest X-ray
• C. Arterial blood gases (ABGs)
• D. Echocardiogram

Correct answer: A

Rationale: The correct answer is an Electrocardiogram (ECG). When a client with a history of atrial fibrillation presents with new-onset confusion, an ECG is crucial to assess for cardiac ischemia, which could be a potential cause of the confusion. A chest X-ray (Choice B) is not typically the first-line diagnostic test for evaluating confusion in a client with atrial fibrillation. Arterial blood gases (ABGs) (Choice C) are more useful in assessing oxygenation and acid-base balance rather than the cause of confusion in this scenario. While an echocardiogram (Choice D) provides valuable information about cardiac structure and function, it is usually not the initial diagnostic test needed in the evaluation of acute confusion in a client with atrial fibrillation.

2. The nurse is caring for a client with acute kidney injury (AKI) secondary to gentamicin therapy. The client's serum blood potassium is elevated. Which finding requires immediate action by the nurse?

• A. Anuria for the last 12 hours.
• B. Tachycardia and hypotension.
• C. Decreased urine output.
• D. Elevated blood urea nitrogen (BUN) levels.

Correct answer: A

Rationale: The correct answer is A. Anuria for the last 12 hours. Anuria, the absence of urine output, indicates complete kidney failure and is a medical emergency that requires immediate attention. In acute kidney injury (AKI), the kidneys are unable to filter waste from the blood effectively, leading to a buildup of toxins and electrolyte imbalances like elevated blood potassium levels. Tachycardia and hypotension (choice B) can be seen in AKI but do not reflect the urgency of addressing anuria. Decreased urine output (choice C) is concerning but not as critical as the absence of urine production. Elevated blood urea nitrogen (BUN) levels (choice D) are indicative of kidney dysfunction but do not demand immediate action as anuria does.

3. A female client reports that she drank a liter of a solution to cleanse her intestines but vomited immediately after. How many ml of fluid intake should the nurse document?

• A. 1000 ml
• B. 800 ml
• C. 760 ml
• D. 500 ml

Correct answer: C

Rationale: The correct answer is 760 ml. One liter equals 1000 ml. As the client vomited immediately after drinking, she would have expelled approximately 240 ml (1 cup). Subtracting this from the initial intake of 1000 ml gives us 760 ml as the remaining fluid intake that should be documented. Choices A, B, and D are incorrect because they do not reflect the correct calculation of subtracting the amount vomited from the initial intake.

4. The nurse is caring for a client with a chest tube following a pneumothorax. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 94%
• B. Subcutaneous emphysema
• C. Crepitus around the insertion site
• D. Drainage of 50 ml per hour

Correct answer: B

Rationale: Subcutaneous emphysema is the correct answer as it is most concerning in a client with a chest tube following a pneumothorax. It may indicate a pneumothorax recurrence or air leak, requiring immediate intervention to prevent complications. Oxygen saturation of 94% is acceptable and does not require immediate intervention. Crepitus around the insertion site may be a normal finding after chest tube placement and does not necessarily indicate a complication. Drainage of 50 ml per hour is within the expected range for a chest tube and does not require immediate intervention.

5. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which clinical finding is most concerning?

• A. Headache
• B. Prothrombin time (PT) of 15 seconds
• C. Elevated liver enzymes
• D. Peripheral edema

Correct answer: A

Rationale: The correct answer is A: Headache. In a client with atrial fibrillation taking warfarin (Coumadin), a headache can be indicative of bleeding, which is a serious complication requiring immediate assessment and intervention. Monitoring for signs of bleeding is crucial when on anticoagulant therapy. Choices B, C, and D are not the most concerning. A prothrombin time of 15 seconds is within the therapeutic range for a client on warfarin, elevated liver enzymes may indicate liver dysfunction but are not directly related to the medication's side effects, and peripheral edema is not typically associated with warfarin use or atrial fibrillation in this context.
